Muscorum, pl. 71, f. 23, and that this figure undoubtedly represents 
J. quinquedentata as understood by later authors. He maintains 
further that this opinion is supported by the specimens in the Dillenian 
herbarium and quotes Lindberg as his authority for this statement. 
Unfortunately Lindberg is not quite so definite as Schiffner implies. 
In the latest of the three works quoted, Kritisk Granskning af Mos- 
sorna uti Dillenii Historia Muscorum (Helsingfors, 1883), he says 
(p. 41) that the figure of Dillenius and the corresponding specimen in 
his herbarium represent a mixture of Bazzania trilobata (L.) B. Gr. 
and J. quinquedentata Huds. According to his account the portion 
of the figure showing the vegetative leaves is drawn from the B. 
trilobata, while the terminal perianth is drawn from the J. quinqueden- 
fata. lt is to be regretted that the evidence in favor of Hudson's 
species is not absolutely conclusive. At the same time the fact that 
the perianths in the Dillenian figures and specimens belong to J. 
quinquedentata as now understood is perhaps sufficient justification 
for the use of Hudson's specific name. In the writer's * Revised List 
of New England Hepaticae” ! the name Lophozia quinquedentata is 
therefore taken up instead of L. Lyoni, and this usage prevails in the 
recent works of K. Müller, Macvicar, and other European hepaticolo- 
gists.

Bull. Herb. Boissier IT. 3: 335. 1903. The name Plagiochila Sulli- 
vantii was originally given by Gottsche to the specimens distributed 
by Sullivant in his Musc. Alleg. No. 219. These specimens were col- 
lected “in sylvaticis montosis Virginiae" and were referred by Sulli- 
vant to the European P. spinulosa (Dicks.) Dumort. Gottsche in- 
cluded under his P. Sullivantii a second specimen from North Carolina, 
preserved in the Lindenberg herbarium at Vienna. Unfortunately 
he neglected to publish a description of his new plant; it remained as a 
manuscript species in his herbarium. When the writer published 
his “Notes on the North American Species of Plagiochila," in 1896, 
P. Sullivantii was among the species proposed as new. It was under- 
stood, however, in a somewhat broader sense than the species of 
Gottsche and was made to include not only the two plants which he
